From eco-friendly home composters to super quick pizza ovens and inventive garden lighting, we look at seven garden products of the year.

Want a composter with a difference? Or a light that doubles as a Bluetooth speaker? Or even a pot or seed tray made from bamboo?

These are just some of the finalists for the RHS Chelsea Product of the Year title which may take your fancy in the coming months, whether you're looking for the practical, the sustainable or the high tech.

Here are 7 clever products which have impressed the RHS judges:

1. Obelisk Composter and Obelisk (£39 composter, £59 obelisk, wilstone.com)

This ingenious invention launching at RHS Chelsea Flower Show features a galvanised mild steel compost bin which you put directly on to your flower bed or in your vegetable patch, and an elegant obelisk which goes over it which you can use as a support for anything from climbing beans to sweet peas or clematis.

You scoop compostable waste directly into the drum and the resulting compost inside then feeds the growing plants directly into their roots without you having to lift or carry the compost anywhere.

2. Cuba LED lantern and combined Bluetooth speaker (£249, lightinnovation.com)

Shed a little light on your patio and enjoy music at the same time with this new lantern and combined Bluetooth speaker, which will be available from the end of May.

It's highly portable and can be used indoors or out, recharging from 0 to 100% in six hours. The dimmable 7 watt LED light will work for up to eight hours on one charge and the lantern will connect to any Bluetooth-enabled device, from a phone to a tablet.

3. Swan Watering Can (£8, madewithhusk.com)

With an emphasis on sustainability, this swan-shaped indoor watering can (to be launched on May 20) is fully biodegradable and made from 75% waste bamboo powder collected directly from farms. Testing has shown that the product can last up to seven years, although this was based on a pot that had been left outside, so it's likely that if kept indoors, it will last longer.

4. Hotbin mini (£150, hotbincomposting.com)

Following in the footsteps of the award-winning Hotbin which can transform your food and garden waste into rich compost within 30-90 days, its smaller sister, the Hotbin mini (launching at Chelsea) does the same thing but is easier to house in smaller gardens.

It reaches temperatures of 40-60C which allows the efficient composting of more types of waste, more quickly. All food and garden waste can be added in, including cooked food, small bones and perennial weeds.

It's also sealed well enough, with a bio-filter in the lid, to stop odours that can attract rats and flies. Add a bulking agent such as wood chippings to aid the process.

5. 'Grande' Plant Belles (from £53, will be available to order from Chelsea plantbelles.co.uk)

To mark the company's 10th year of trading, it is launching three new 'grande' plant belles, elegant but robust steel wire frames to support larger freestanding herbaceous plants, unruly shrub roses and other floppy heavy headed shrubs like Hydrangea 'Annabelle'.

The new taller, wider and heavier plant belles are inspired by the Sissinghurst method of training shrub roses, offering needy plants support once grown through, but also give the gardener the chance to prune and train shrubby plants in creative ways, by looping and tying branches back to the structure.

6. Ooni Koda Gas-Powered Outdoor pizza oven (£244.99, uk.ooni.com)

If you love eating pizza in the open air and you don't want to wait too long, you may invest in this smart, sleek pizza oven which you can assemble in seconds, place on your patio and have a pizza ready in 60 seconds.

Flip open the foldable legs, put the stone baking board into the oven, connect it to a gas tank and pre-heat the oven for 15 minutes. It reaches temperatures of up to 500C, which is why it can cook your pizza so quickly. It has a clean, streamlined silhouette paired with one-touch gas ignition for easy, convenient outdoor cooking.

7. Bamboo Pots and Seed Trays (£3.99-£6.99, www.haxnicks.co.uk)

Continuing the eco-friendly theme and the war on plastics, these bamboo pots and seed trays from Haxnicks are made from bamboo and rice, can be used indoors or outdoors and are reputed to last for five years or more. They're also biodegradable and compostable, so give a feelgood factor to gardeners who really care about their environment.
